Seismic Performance Analysis Of Reinforced Concrete Frame Structure Consider The Floor Slab And Infilled Wall Effect

Frame structure with characteristics of architectural functions flexible layout, greater space for use and mature design theory, are widely used in engineering practice in our country. Previous studies and actual earthquake damage showed that, cast-in-situ floor slab and masonry infilled wall have a great influence on the frame structure seismic performance. In Wen Chuan earthquake the frame structure damage often does not meet the "strong column weak beam" design guidelines. Our specification does not fully consider the impact of both, further research is needed impact Slab and masonry infill walls on seismic performance of reinforced concrete frame structure.In order to research the frame structure seismic performance effect of slab, based on the specimens which research group had, verify the validity of ABAQUS propose the recommended values of effective flange considering the influence on the effective flange width size of beam section, plate width, thickness on the basis. Under the proposed value, three space frame model were designed and analyzed by pushover method, plastic hinges lateral bearing capacity of the structure, the interlayer displacement and destruction mechanisms were analyzed and compared, the results showed that reduce the beam reinforcement area considering slab effect one structure can achieve "strong column weak beam." Different seismic level framework were designed and pushover analyzed taking into account different column increases and beam moment adjustment factor coefficient, the influence results obtained in different regulations of02specification and10specification, and put forward some suggestions on the actual design. In this paper, nonlinear model of masonry infill walls comparative analysis to study the effect on the overall structure filled with wall bearing capacity, stiffness and ductility of masonry infilled with oblique strut model pushover analysis, study of masonry infill walls impact of the seismic performance of frame structures, and put forward some suggestions on the actual design.All in all, the study on seismic performance of frame structure from the floor slab and infilled wall with both is comparatively comprehensive and systematic, which provides more theoretical basis for further research, the specification revision and relevant engineering application.
